The Effect of Selective PDE-5 Inhibition on Capillary Recruitment, Glucose Uptake and Endothelial Function Following a Mixed Meal in Patients With Type 2 Diabetes Patients
Abstract
An increase of blood flow and capillary permeability decrease the impact of an endothelial barrier for glucose and insulin allowing them to reach their target cells in peripheral insulin sensitive organ in the human body. It is well known that insulin-resistant type 2 diabetes patients have an impaired blood flow in skeletal muscle and it is therefore important to elucidate means to reverse this metabolic defect.
The investigators have in a recently published study in type 2 diabetes patients used a drug against erectile dysfunction, the PDE-5 inhibitor tadalafil, with known effects on several vascular territories, to increase muscle blood flow in type 2 diabetes patients who were studied after fasting overnight.
The aim of this study is to test the hypothesis that tadalafil, compared to placebo, increases muscle glucose uptake and lowers blood glucose following a mixed meal served to type 2 diabetes patients.
Conditions: Type 2 Diabetes.
Primary outcome: Capillary recruitment, muscle glucose uptake and circulating glucose levels following a meal.
Enrollment: 22 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 22 participants or records.
